Abstract

A golf club includes a hollow conical middle tube having a first end provided with a head and a second end provided with a grip. The middle tube includes an upper rod and a lower rod. The golf club further comprises a connector mounted between the upper rod and the lower rod, so that the upper rod, the connector and the lower rod are combined to form a conical rod. Thus, the connector can absorb and eliminate the shock produced by the head rapidly and actually, thereby preventing the shock from being directly transmitted to the grip so as to protect the user's hand.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
       1. A golf club, comprising a hollow conical middle tube having a first end provided with a head and a second end provided with a grip, wherein: 
       the middle tube includes an upper rod and a lower rod;  
       the golf club further comprises a connector mounted between the upper rod and the lower rod, so that the upper rod, the connector and the lower rod are combined to form a conical rod;  
       the lower rod of the middle tube has an inner conical hole for insertion of the connector;  
       the connector has a center having a passage co-axial with the middle tube;  
       the connector has a first end provided with a first smaller diameter portion and a second end provided with a second smaller diameter portion;  
       the first smaller diameter portion of the connector has an outer conical portion inserted into the inner conical hole of the lower rod;  
       the first smaller diameter portion has a centring section and a fixing section;  
       the centring section of the first smaller diameter portion is closely positioned in the inner conical hole of the lower rod;  
       the fixing section is a helical groove and is provided with an adhesive, so that the first smaller diameter portion is closely fixed in the lower rod;  
       the second smaller diameter portion of the connector does not have an outer conical portion;  
       the second smaller diameter portion of the connector has a helical groove which is provided with an adhesive, so that the second smaller diameter portion of the connector is inserted into the upper rod of the middle tube, the connector is closely fixed on the upper rod of the middle tube, and the upper rod, the connector and the lower rod are co-axial with each other;  
       the golf club further comprises a composite layer mounted on a periphery of a combination of the upper rod, the connector and the lower rod; and  
       the composite layer consists of a metallic filament and fiber.  
     
     
       2. The golf club in accordance with  claim 1 , wherein the connector is made of aluminum. 
     
     
       3. The golf club in accordance with  claim 1 , wherein the metallic filament of the composite layer is made of titanium.
